DRINKING-TUBE.

- SPECIFICATION forming part of Letters Patent No. 599,893, dated March 1, 1898.

Application filed July 17, 1896. Serial No. 599,485. (No model.)

To all whom it may concern: part being suitably formed to telescope Be it known that I, JOHN A. CLARK, of preferably over and iit tightly upon the end Worcester, county of Worcester, and State of of the part c. The part c, as herein shown, Massachusetts, have invented an lrnprovehas its inner end curved or drawn gradually 5 ment in Drinking-Tubes, of which the followinward, as at 0 and at its outer end is proing description,in connection with the accomvided with an inturned rim to hold the fopanying drawings, is a specification,like letraminous diaphragm 0 The outer end of ters on the drawings representing like parts. the other part c of thefitting is also provided This invention has for its object to provide with an inturned lip to sustain the outer foxo anovel and improvedtube which maybe conraminous diaphragm 0 When in position, veniently carried by bicyclists, pedestrians, the outer part c is prevented from being and other travelers and by means of which pushed completely onto the inner part either the user may drink from streams and the like by its end striking the end of the rubber tube, without stooping with his mouth to the water as in the instance shown in the drawings, or 15 and without danger of drawing in insects or in other suitable manner, so as to leave a foreign matter which may happen to be in the chamber c between the foraminousdiawater. phragm of the two parts of the end fitting and 'In the drawings illustrating my invention, within the outer part c.

The mouth end 6' is of course perforated, the inner part c. The diaphragm b in the as at 6 and is made removable in order that mouthpiece effectually prevents any possible it maybe thoroughly cleansed when necespassage of foreign matter to the mouth of the sary and also to permit access to the foramione drinking. o 1 nous diaphragm b with which the nipple Z9 My invention also comprehends the intro- 40 is provided. The foraminous diaphragm b is duction between the entrance of the tube of herein shown as insertedfrom the innerend of the compressible bulb D, which may be in the nipple b and seated against the shoulder open communication at both ends with the or ledge 12 and formed about the interior paslengths of the tube between which it is in- 5 sage of said nipple, and, if necessary, the enserted. By compressing the tube above the 45 tire nipple may be withdrawn in order that bulbfor instance, at the point l-between access to the diaphragm may be had on both two of the fingers and after compressing the sides for perfect cleaning. At its opposite bulb and permitting it to again expand a end the tube a.is fitted with a suction-fitting quantity of water represented by the capacity 0, herein shown as composed of two telescopof the bulb and the length of the tube be- 5o ing parts 0 and c, the part 0 being suitably tween it and the suction end C is drawn into formed for insertion in or to be otherwise atthe device, and then by relieving the pressure tached to the suction end of the tube, the above the bulb compression of the latter will force the water contained within it and above the point at which the tube below the bulb is compressed upwardly into the mouth of the drinker.

My improved device, as herein set forth, while easily portable, effectually guards against passage of foreign matter with the water to the mouth of the one using it, and while a filtering material may be placed between the two suction-diaphragms c 0 yet I prefer to use the device without any such material, which would soon .assume a condition which would render the use of the device undesirable.

The readiness with which the several diaphragms and the entire device may be cleansed is an important feature of my invention, which is not necessarily limited in all respects to the particular embodiment herein shown.

hat I claim is- 1. A drinking device, comprising a flexible tube, a two-part mouthpiece applied at one end of the tube, said mouthpiece comprising a nipple interiorly threaded, and a month end screwing removably into said threaded nipple, the latter also having an annular shoulder b adjacent the inner end of said mouth end and facing inwardly, and a foraminous diaphragm b removably mounted against said shoulder, and a suction-fitting applied at the opposite end of the tube, said fitting being composed of the two telescoping parts a c, and one or more separable foraminous diaphragms arranged in the said suctionfitting, substantially as described.

2. In a drinking device, the combination with the flexible tube and the mouthpiece supplied at one end' thereof, of the two-part suction-fitting applied at the opposite end of .the tube, the two parts of said suction-fitting removably telescoping one within the other and being provided respectively with a foraminous diaphragm, said diaphragms, when said parts are telescoped into operative position, being separated to leave an empty chamber between the two diaphragms for the purpose specified.

The combination with the flexible tube, of a mouthpiece supplied at one end thereof with a two-part suction-fitting applied at the opposite end thereof, one part of said fitting telescoping the other, and foraminous diaphragms on the respective parts of said fitting, to operate, substantially as described.

4. In a drinking device, the combination with a flexible tube and a flexible bulb introduced intermediate the ends thereof, of a mouthpiece applied at one end of said tube, and a removable suction-fitting on the opposite end thereof, said fitting comprising two telescoping parts 0, c, and one or more foraminous diaphragms arranged in said suction-fitting, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN A. CLARK.
